G1 shuts off randomly and thinks it's dead?

Hey, guys, I tried dong some research but I can't find anyone with a similar problem.
I've got a T-Mobile (USA) G1 and I've got Cyanogen's Eclair ROM flashed on it. Prior to flashing Cyanogen's ROM, I was using OpenEclair. OpenEclair was working [relatively] well until my phone randomly started shutting off. I thought it was a battery calibration problem, so I recalibrated my battery by letting it die completely and then charging it fully, but that didn't work. I flashed Cyanogen's Eclair and hoped that my problem would be fixed, but the problem still persists.
I can't really isolate the problem. My phone can shut off in the middle of a call, in the middle of writing a txt message, or without me even using it while it's in my pocket. It shuts off regardless of the battery level (I've seen it shut off at like 97%). This wouldn't be THAT bad except the phone refuses to turn on right after it shuts off. When I press the power button, the phone will show the G1 logo for a few seconds and then shut off again as if it was dead. Sometimes if I press the power button, the phone won't turn on and I'll see the LED flash red which gives me the idea that the phone "thinks" it's dead. In order for me to turn the phone back on, I need to plug in the charger. This is becoming extremely annoying.
Does anyone know what the problem could be? I would try wiping/re-flashing but I don't wanna lose all my data :/
Thanks,
Gerard

I'm having the same exact problem ever since installing cyanogen 5.0.7 Test 1... so im not sure whats going on but i went to T-Mobile today... and they said my battery is warped or somethin not to tech savy... yet it was working fine like totally so... hmmm anyone know anything?

yea this has happened to me too! It shuts off randomly then i cant turn it back on until like 30 minutes later without touching it. I noticed that it happened after i flashed a open eclair rom that wouldnt start but i did flash it correctly. I have wiped battery stats and dalvik cache. Well i hope we can get some answers

I had the same problem I have tried just about every rom out there so dont remember when it started but i ordered a new battery off ebay for 10 bucks and havent had a problem since

So you think it's a hardware problem? I find it kinda hard to believe that all of us coincidentally got this problem after installing Ecalir ROMs...unless Eclair destroys our battery somehow?
:/

yeah same here but mine started with Amon Ra 1.2.3 and the blue haze rom. I updated my recovery to the latest 1.6.2 I think and switched to htcclay's superfast and the danger spl slso tmobile is comping me a new battery just to be safe, although switching rom's seem's to have helped my battery life a little. hope this helps someone.

Have you tried replacing the battery?

Nah, I'm part lazy and part unconvinced that it's a hardware issue. I mean if the phone reads that the battery is like 95% charged, why would it just give out randomly? I don't know much about hardware though, so maybe I'm wrong...
I want T-Mobile to get a new Android phone that's like incredible I want a new phone already damnit!!

im just gonna buy a battery on ebay or something because my battery does look kinda swollen so it could possibly be the battery. Gonna give it a try though

You think you could update us when you find out whether it changes anything or not? :/

This phone gets me really frustrated because first it started shutting off and now i have a unresponsive lock screen! I push all the buttons and the screen is black like if its turned off. I have to do a battery pull but theres a risk of the phone not turning back on and shutting off on the g1 screen. I was planning to buy the battery today but i think im just going to use a different phone for now. I hope someone can really resolve this problem. Cant wait for the samsung galaxy s

For what it's worth, I started having the same issue last week with my G1. I think it's entirely coincidental that you switched to the CM 2.1 Test branch and your phone started getting screwy.
I looked at my battery as the first suspect, and what did I find when I pulled it out of the case? A badly swolen battery. By the end of the week, the swelling had gotten so bad that it was visibly bulging the plastic backing on my G1.
I took it to 3 separate T-Mobile stores looking for a replacement battery. The first two were of no luck, but the 3rd finally had one in stock. The CSR saw my battery and almost freaked out. She says I was lucky that it didn't pop because it was ready to at just about any moment.
Long story short, since replacing my battery, I have had ZERO issues, and my battery life has once again been phenomenal (well, for the G1).

I just checked my battery and I think it's possible that it's swollen. On the side where it says "htc Innovation," is it supposed to be perfectly flat? There's like a rectangle that's slightly raised above the rest of surface. I'm a little hesitant to buy a $50 battery if that's the way the battery is supposed to be.
Thanks,
Gerard

Spontaneous power off - sunspots?
Yes, this happened to me fairly frequently about 3 months ago. Now it happens (maybe) once a week.
In my experience, it isn't a Cyanogen issue - it would spontaneous die when I used Enomther's official rom, SuperD (one of the previous versions), and some others. That made me think it was hardware, but ... I haven't changed hardware, and still drop the G1 into my pocket like usual.
So if it isn't ROM software and it isn't hardware, what is it - sunspots?

It should be perfectly flat. A new, good battery does not have the bulging rectangle in the middle you are talking about. Mine did the same thing. In fact, both sides were swelling. The battery would no longer sit flush in the back. My theory was simply that some sort of movement was causing it to lose contact and shutting off the phone.
If you take the battery out and lay it flat the table, you shouldn't be able to rock it by pressing an edge. If you can, your battery is dying.

I just bought a battery yesterday on amazon for 15$ You should check it out. Hope this battery resolves my problem. I also fixed my lock screen issue. I had set cpu to 120 instead of 128 so it unresponsive.

I have the same problem, and indeed when i now look at it my battery seems a bit swollen. I ordered a replacement battery on dealextreme. They have a few different battery replacements for the G1 for cheap (and lots of other things, regular customer) with free shipping. So i hope that will fix my problem .

I found this thread because I've been having random shutoffs as if the battery were pulled (black screen immediately, no "Shutting Down" prompt first), and it would only do this when NOT charging. This started happening when I first ran Firerat's all-in-one script but I think it was coincidental. So anyways, I found this thread after wanting to pull my hair out because of the random shutoffs, and sure enough, I pulled my battery and it's a bit puffed out. Time for a new battery.
My question is : does anyone think this is a result of the extra strain placed on the battery / heat generated from being overclocked? Once I get a new battery, I'd like to prevent it from happening in the future.

definately a battery problem. had the same thing on my g1. got into a whole big argument about how it WAS NOT PHONE in the cyanogen6 thread. guess what....it was my phone.
its not the rom. its your phone. seriously.
also, just to point out, most of us here got our phones relatively early in its release, and lot of people are having this problem now apparently. battery has life of 2yrs by my calculations.
if you can mimic a reboot with the phone plugged into usb or wall charger...it may be rom. but if you phone DOES NOT DIE while PLUGGED IN...ITS YOUR BATTERY.

Had the same problem with my 2008 bought g1, swollen battery and random shutdowns. Just inserted an new bought battery. Hope it fixes the problem.

I have the exact same problem, am about to buy a new battery tomorrow unless someone else has another solution? This might not be the proper forum but in here at least many i9001 users will read it.
I've had this problem for about a week, was very annoying while on holiday. I've tried using BroodROM BE 1.0, Stock KQE and now back to stock KPG.

Well yes I'm going to try a different battery soon but the odd thing is after my battery charge seems to drop down to 5% or so, it starts charging to about its original charge level without a charger connected. So it's basically 80%->drop to 5%->charge back to 60% without charger.

i'll try now to do a hard reset, go back to stock rom, then reinstall an costum rom,
will tell you if it works!

Plz mods remove/delete this sheeyat.. this is

i have used TeamWin Recovery for wipe all partition becouse with hard reset don't wipe /system and internal sd.

I thought I was the only one with this problem. I charge my battery to full and it starts draining normally. Then, when around 30-80% battery remaining, it turns off. It only turns off when you use it for a while, when the screen is off it stays on normally. After rebooting it turns off within a minute or so. This continues for a few reboots with the battery level remaining roughly the same. Eventually after a few boots it shows 3-4% of battery, after which I of course have to charge. Also tried calibrating and tried different roms but it still remains. I ALSO SWAPPED MY BATTERY WITH A FRIEND BUT IT DIDN'T HELP! It worked like a charm for him but I still got turn offs with his battery.

If i were you Guys, i would install stock rom and hand in my phone under warranty ( of course if you still have it ). Because if this occurs even when u swap battery, let samsung play with you phone then

Its not your battery..restore your phone to the way it was and give it to samsung

i'm getting pissed of now, even with the stock rom it randomly shutsdown.
i don't have any warrenty so i can't give it back to samsung

In case anyone's still wondering, in my case it did turn out to be a fried battery. If anyone else is experiencing the same issues I was, just check your battery to see whether or not it is swollen. If it's bigger than it should be, that probably means it's fried and you should replace it. I'm happily running custom roms without any trouble again now, and battery life is awesome!

Sorry Rajito, but you are having a serious problem, i think the motherboard is the problem, my friend had the same problem with his I9000 S simple. You shoud go to a service !

Hi guys,
I also have this problem, my phone randomly turns off and when I turn it on, it shows much less remaining battery percentage than before. (please see attached image) After turning on the value is increasing, sometimes from ~5% to 30-40% or more...
Now I have CM10 Jelly Bean flashed, but CM9 did the same sometimes but much more rarely than on JB. Today the phone 'died' three times until noon.

Yeah that's the exact same problem I had. In my case it turned out to be a fried battery, see if it's swollen or not, if you lay your battery on a table it should stay still and not wobble around. If the battery's not flat but swollen that means your battery is fried. In this case good news because you can easily replace it

unfortunately it is absolutely not swollen, its fully flat :\
besides this I put out the battery now and put it back and it is showing only 2% percent of battery so maybe my battery is wrong
UPDATE: after uninstalling the pro version of Battery Indicator there were no random shutdowns at all, but the free version is fine o.0

Random crashes with ICS roms [i9001]

Search didnt help, and cant post on development section yet.
So my problem is with pretty much all ICS roms ive tried, but currently i am running CM9 RC3.
So my phone randomly crashes, when im listening to music with apollo and dspmanager running. sometimes it just crashes in my pocket, sometimes it crashes when some one calls me while im scrolling songs etc, sometimes it just crashes without doing anything, but the weird thing is that everytime my phone crashes, theres a 50/50 chance to boot it, sometimes it boots but battery can jump from 80% to like 14% etc..
sometimes it can jump from 80% to 0% (?) and when that happens my PIN code doesnt register and the phone will just crash in seconds.
But usually i have to take battery out, wait a sec then it usually boots but battery always drops to 4-20% and starts charging on its own..
Before installing i have done full wipe, fixed permissions, calibrated battery, used CWM 5.5.0.4, tried ODIN (no luck with that either).
I flashed Broodrom (GB) And it crashed also with same problem..
Ive tried BioHazard rom, same problem, but when i flash stock ROM, no crashes..
Pls halp
E: Forgot to add, sometimes when it crashes its stuck on bootloop until i take battery out, after that it MIGHT boot, not always. But it never crashes when on charger..

So im guessing im alone with this problem

What do you mean crash??
Does it restart or apps just ForceClose??
If it restarts, does It begin from the beginning of the boot cycle or just the boot animation??

I have the exact same problem with my i9001 since 3 weeks now. It started when flashing broodrom and now happens with any ROM (I have tried a few, cleared cache, format system, etc....). Even the battery behaviour is exactly the same as you describe..
To answer the question: the phone restarts from the Samsung boot screen. IF anybody has any clue, it would be great to hear... It's a very annoying issue I can tell you!
Thanks in advance!

Thats something you should take note: your battery is most likely dying.
I had the same exact issue: Started with the stock ROM, flashed Paranoid but it continued. Took it to service (with a stock ROM), came back re flashed and wiped. The same thing continued, no matter what ROM I was using so i figured it had to be a hardware problem.
I noticed that my battery had swollen a bit, like 1-2 mm so that I could see it easily: the battery should be flat, mine was not. Borrowed a battery from a friends I9001 and got no crashes after 15 minutes of heavy use: problem solved!
Bought a new battery and haven't had a problem since.
The battery has only 6 months warranty and my phone was a year old, I kept the old one as really crappy spare battery.

Sorry guise, forgot to post here!
I bough a Polarcell 1800mAh battery and no more crashes, my old battery had swelled, if yours is also its pretty easy to notice, i just put my credit card on top of the battery to check it.
So yeah, you have this problem, new battery, thats all.

Hi. Thanks for the quick replies!
I have actually just tried to exchange batteries with a friend having the same phone --> his phone crashed, mine did not anymore. I then saw by carefully looking at the battery that it had indeed maybe a 1mm swell in the middle. Just ordered a replacement one. I am confident this will fix the issue.
Again, thanks for your reaction.. Nice to see the responsiveness of this forum!
Cheers,
G.

If its the exact same problem, you need to change battery and test or try connect to charger and test

i have same problem mostly with app using gps.
today i have installed the new app game from google called ingress and it makes my phone always.
i found a new battery and i will try if something will change.
lately my crashes happens very more often i am using a gigabread+ rom and cwm recovery, but was quite the same when i was in stock .
(sorry for my english)

I got same problem with my phone, first phone gets frozen/stuck and then reboot itself from bootscreen. This was totaly random issue. After trying several roms, and kernels, underclocking cpu, I found that problem is in external sdcard. I think this is battery related issue. After unmounting and removing external sdcard, reboots gone, and battery lasts at least 20% longer. Im not using my phone like external storage, so I dont miss external sdcard, I got quite enough space on internal.

Problem fixed!

I found out that my SIM card was corrupted and caused my phone to be unable to boot. And the random shutdowns with sudden battery drains were fixed by changing the battery

[Solution] Flickering screen, poor battery backup, sudden discharge [n7000, Note]

A month or so back I started facing weird problems with my year old Galaxy Note, n7000:
1. After reboot, the battery would go down by 15-20% and then without charging the battery %age would gradually increase by 5-10%
2. lots of flickering on screen followed by auto shutdown whenever the battery %age went below 15-20% after normal usage
3. Very poor battery backup (I blamed most of this to the Rom Mods I had been installing at that time- only partially correct!)
I am sure that many of you might have been facing such problems and running from forum to forum to get a solution- I did.
Solution:
Get your battery replaced- most of us have had our Note for a year and some months now...life of the battery is approx 1 year for regular use, thus, the stock battery that we got with our Note is well past....
I never faced the above problems after battery replacement!
Hope this helps others like me!!

I started having this problem after getting a new battery, my old battery which was weak never showed flickering. But this new one which is original samsungs battery at below 15% show flickering and sudden discharge despite a good battery time.

I got rid of the damn problem after getting new ones...Is it possible that the batteries you bought are not genuine/fake?
Which ROM are you on- the Stock one or some mod-rom?
When I was searching for a solution to my battery issues some members suggested battery-calibration and full charge-full discharge cycle to get rid of the problem. Both the solutions suggested at that time did not work for me.
There was also a solution about cleaning the mini-USB connector which gets seriously dirty collecting grime from our pant pockets! That did work for me initially when the battery was good.
Please let me know if any of the above helps you.

Guys - Me too have the same issue, but this started immediate after updating the Jelly Bean 4.1.2. It never happened while on official ICS.
I could observe the battery is very much thick now, which is a symptom of over charging. The screen flickers and brings phone down abnormally.
After connecting the charger for a 5 seconds, suddenly the battery level shoots to original state from where it went down. Most frustrating, it happens very frequently.
I am not sure if the same will persist even after replacing with a new battery. Or I would need to go back to ICS again.
Any suggestions?
Cheers!

If the battery is bloated then it's better to get a new one.

Erm... is this thread still up?
I just wanted to know if the bloated battery would cause boot issues, stuck on the model screen?
I would guess the problem is with the bloated battery's voltage is insufficient to power up the systems... i guess
I need confirmations... thank you in advance

4.1.2 xxlsz deodexed by eybee
The problem is, after I restored most of my data, apps and system data separately, the screen flickers a little bit and then the restore process completed without any problem. After that I restart the phone, stuck at the model screen only for unknown reason. The data is also from previous xxlsz which I had trouble with some system app crashed but fixed by returning to another backup though.
So, currently I'm leaving the phone without any data restored, only stock fresh out of the box xxlsz with titanium backup only installed. So far the phone is quite stable, I've turned off the adaptive power adjustment in display as well as lowest brightness just in cast it might occur again.
I've been reflashing xxlsz a lot this morning, over 3-5 times due to stuck in boot logo and model screen. Even though flashed the latest philz 4.90.8, it would just revert back to the old philz 4.8x with cwm 6.0.2.8
One last thing, my batter bloated pretty bad about half of it has been expanded. I mean from the bottom part (no copper connections), half of it has reached out of the body.

Well,
hppend to me b4, flickering issue below 10%. It was bloated. Bought new one. Bloated again after 6months. Again, bought a new one and it can last only 7 hrs without switch on data.
This is what we get from massive production company.

Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD

@amogh you can check your battery voltages and battery temperature and compare that to optimum values. you can also use apps like AnTuTu battery tester.

Flashing another rom again wont solve much of the problem, if you happens to have the phone stuck in around bootloop and able to go into cwm, brace yourself, this process can get very repetitive to solve because a mere battery able to do such a problem. I had these experience before about 2 months ago before buying a new battery. Hope this link helps you understand a bit more of the battery

[Q] Weird unprovoked Jellybean Samsung logo brick question

Hi,
A few days ago I upgraded my Note from a very ancient (stock) Gingerbread ROM to (stock) Jellybean. I hadn't been getting OTA updates because the Gingerbread was originally German rather than UK, so quite a long time had passed without any updates. Anyway, because of the no OTA, I used Odin. Everything went fine and I had a nice few days of usage, although the battery consumption seemed to suddenly be quite high, mainly due to additional wakelocks from the new Google Search it looked like. The night before last at about 3% the phone turned itself off, which is unusual as normally the battery will run itself lower than that. BTW, it's an official battery bought just a few months ago to replace the one before, which was getting old.
Yesterday evening when I went to use the phone it was dead. Completely unresponsive. It wouldn't charge either. (The battery had been at about fourteen percent I think, so it should have still had a lot of juice left.) Turning it on would leave it stuck on the Samsung logo only. Recovery mode didn't work, but I could get download mode up, so I installed the Philz kernel as people have said, and then did a reset using that, and all was okay again and after reflashing the ROM I could use the phone again, although because of the reset I had to set everything up again.
Just wondering what people think caused it. Just a weird coincidence, or something else? As far as I'm concerned, the problem has been sort of mitigated for now, but definitely not fixed, because what's to stop it happening again? Has anyone heard of strange things going on with Jellybean? I know there's an issue with flashing/resetting from ICS, but I never used that so I don't think that's an issue, and it looks like it was just a soft brick only. Still, a bit weird and worrying. Does anyone have any ideas?

That was caused by an unexpected shutdown of your phone - if you remove the battery without it fully turning off then you will get it and yeah, blame samsung.
The only way not to have it again is to flash philz kernel with the bootloop fix BEFORE you get the bootloop. Alternativly, if you get it again then you can try what is in this post:

I didn't take the battery out though. It was low but not dead.
Since then it has happened once again, a few days ago, this time at 93% full. I was doing nothing at all taxing to the phone. I was just in a shop listening to an mp3 with the screen off, and then it stopped and the next thing I saw was the bootloop. Luckily (thanks to the new kernel?) I could just delete cache/dalvik and be back up and running again without having to reinstall everything. Today my screen temporarily went a weird purple colour like in this thread: http://forum.xda-developers.com/showthread.php?t=2216867 . Sounds like it's just dying in general really, rather than anything else. My phone contract upgrade date is in two days. Purely a coincidence of course. Weird how phones tend to last about the length of a mobile phone contract. Until then I'm just running on power saving mode and hoping for the best.
